adding unit tests for custom swatch colors (#4025)
* adding unit tests for custom swatch colors * Update tests/MaterialColorUtilities.Tests/CustomSemanticSwatchTests.cs Co-authored-by: Kevin B <Keboo@users.noreply.github.com> * Fix redundant loop in CustomSemanticSwatches test The test method was using a nested loop that shadowed the `isDark` parameter, causing redundant executions. This change removes the inner loop and uses the parameter directly. --------- Co-authored-by: Johann Dirry <johann.dirry@microsea.at> Co-authored-by: Kevin B <Keboo@users.noreply.github.com> Co-authored-by: Kevin Bost <kitokeboo@gmail.com>
